With a quake as large as this, the likelihood of further aftershocks and additional damage is fairly high. These numbers are subject to a fairly wide margin of error because as we reported earlier this year, measuring earthquake epicenters is an imprecise science. A 5.9-magnitude earthquake struck southwestern Alaska on Tuesday afternoon, causing moderate shaking that was felt in Anchorage, the U.S. This slow collision also helped cause the volcanos that created the Aleutian Islands.īut the November 30th quake, which had an epicenter roughly 20 miles north of Anchorage and 25 miles underground, does not seem to be directly related to the Aleutian subduction zone, according to the US Geological Survey. Rather than slip smoothly, the plates grind together and build up stresses in the earth’s crust that, when released suddenly, serve as the source of many of the region’s earthquakes. The plates are constantly moving against each other at very slow rates-typically just a few centimeters per year. We removed the state from our in-depth analysis of seismic activity induced from oil and gas operations, due to the very high levels of natural seismicity along the Alaska Aleutian megathrust-a vast subduction zone just south of Alaska’s Aleutian Islands chain where the Pacific tectonic plate plunges underneath the North American plate. We investigated Alaska early on in the preparation of our comprehensive saltwater disposal well risk report. Approximately three-fourths of all earthquakes in the US with magnitudes greater than five happen somewhere in Alaska. AKST (17:29 UTC), a magnitude 7.1 1 earthquake hit Anchorage in South Central Alaska. While many of these were relatively small seismic events, 31 earthquakes had magnitudes of 6 or greater on the Richter scale. USGS Shakemap for the event On November 30, 2018, at 8:29 a.m. The Alaska Earthquake Center at the University of Alaska at Fairbanks reported more than 150,000 earthquakes in the state in the last five years alone. While this recent quake was large and unsettling to the local populace, it is not a rare event.

A massive 5.0 magnitude earthquake shook Alaska this afternoon after the state experienced the largest quake in the world in 2021. Earthquake activity recorder from November 14-30, 2018. ![]()
